Subject: [PATCH v2] codafs: Fix build using bare-metal toolchain

The kernel is self-contained project and can be built with bare-metal
toolchain. But bare-metal toolchain doesn't define __linux__. Because of
this u_quad_t type is not defined when using bare-metal toolchain and
codafs build fails. This patch fixes it by defining u_quad_t type
unconditionally.

Can you please pull this one, if this applicable? I sent it a while
ago, but I guess it got lost in mailing list. It might be also
applicable to stable branch (as it fixes allmodconfig build for ARM
with bare-metal toolchain).

Thanks!

Sorry to bother you. I just thought you might be interested in this
one, as it fixes build for "allmodconfig" configuration, hence it can
be related to stable branch. Also, maintainers didn't respond to that
patch, so I'm kinda dead in the water.

Anyway, will try to ping maintainers one more time.

I thought I had responded, I didn't see a reason why one would want to
compile non-userspace kernel headers outside of the context of the
kernel and if you do have to do that why not just add -D__linux__.

However, I can also see the point that anything not in uapi/ pretty much
by definition will be compiled with __linux__ defined so it actually
doesn't make a discernable difference to just drop the ifdef and I'm
fine with a patch like this.

These trivial patches typically get picked up through kernel janitors,
or maybe an akpm linux-next patch queue. In fact, I'm not even sure if
there is a designated person I would be passing updates to, I've sent
patches to akpm, viro, hellwig, linus, and gregkh at various times.

Hi Jan,

Thank you for the reply. Good point, I will try to re-send this one to
Andrew Morton and kernel-janitors.

P.S. We need this patch for fixing LKFT/ci-loops build.

Thanks!

I don't see your response either previously or now (currently only via
Sam's reply), perhaps you have an issue with mail delivery?

Andy, btw, I'm observing some strange mail thread behavior here. I'm
pretty sure you responded to Jan, but he's not in the recipient list
in your last mail. If you check Jan's mail (the one you responded to),
you can notice new "reply-to" field (or "Mail-Followup-To:", in raw
mail). When you respond to his mail, you respond to that list. But Jan
is not in that list. That may be the cause of confusion we're seeing
here.

Anyway, mail settings aside, I'm glad this patch has found its way to
upstream. Thanks everyone.
